Air filters for gases, odour and dust
The air filters on Industriële Luchtfilters are for industry, water management and buildings. The range has activated carbon filters, chemical filters, dust filters and complete filter installations. The tests, rental and service that go with them are here too. You choose by the substance that has to come out of the air. We explain which technique fits and why. When we say how a technique works, we name the source. That is a standard or iplo.nl, the Dutch government site on rules for the environment.
Next step: Start the selector (two questions: what has to come out, and how much air)
What has to come out of the air?
Each substance needs its own filter medium. Odour usually comes from volatile organic compounds (VOCs), hydrogen sulphide (H2S) or ammonia (NH3).

What usually works |
See |
|---|---|---|
|
Odour and VOCs, for example from solvents |
Plain activated carbon. The compounds stick to the carbon. |
|
|
Hydrogen sulphide (H2S), an acid gas |
Carbon with an alkaline impregnation |
|
|
Ammonia (NH3), an alkaline gas |
Carbon with an acid impregnation |
|
|
Gases that corrode electronics |
Chemisorption. Alumina grains with a chemical that binds the gas. |
|
|
Fine and coarse dust |
Dust filters, sorted in classes by ISO 16890 |
Source for adsorption and impregnation: Informatiepunt Leefomgeving, Adsorptiefilter (in Dutch). Dust filter classes: ISO 16890.
Not sure exactly what is in the air? That is common. A gas analysis shows only one moment. How a test with a rented filter unit works is explained under Filter unit rental.
What decides which filter fits
Advice starts with the substances in the air and the state of the air. It also depends on how much must be removed and how long the filter must last. See Filter installations.

Products
- Activated carbon filters. Cartridges, modules, panels and loose carbon, for odour and VOCs.
- Chemical filters. Alumina media that bind gases chemically.
- Dust filters and HEPA. Bag, compact and panel filters, and HEPA filters.
- Filter installations. Deep bed scrubbers, air handling units and overpressure units, also turnkey.
All product groups: Products.
Services
- Measurements and analyses. Air tests and samples of filter media. Corrosion is measured too, with copper and silver coupons to ANSI/ISA-71.04-2013.
- Rental. Mobile carbon filter units. They are ready for use within 2 to 3 days.
- Media replacement. A vacuum truck takes the full medium out of the filter. It is taken away, processed and disposed of responsibly.
Sectors
The range is used at water and sewage plants and in industry. It is also used in data centres, archives and museums. And at biogas plants, in shipping, at airports, in hotels and restaurants, and in commercial buildings. In meat plants, odour often comes from blood and waste. At water plants and sewage pumping stations, H2S is mostly the cause.
Need more on one case? We have separate sites for that: corrosion in control and MCC rooms, air in archives and libraries, odour at sewage pumping stations, odour at wastewater treatment plants, industrial odour and process emissions, biogas cleaning and odour filters for restaurant kitchens.
Frequently asked questions
Can I rent a filter unit instead of buying one?
Yes, see Filter unit rental.
What is the difference between adsorption and absorption?
In adsorption, a substance sticks to a solid, such as activated carbon. In absorption, it dissolves in a liquid, as in a scrubber. Source: Informatiepunt Leefomgeving, Gaswasser (in Dutch).
When does activated carbon need replacing?
Before it is full. A full filter no longer works. It can even let substances go again.
